MARIA SHARAPOVA, RUSSIA

Sport: TennisIf you don't know who Maria Sharapova is, you've probably been living in Middle Earth. The 25-year-old Russian-born tennis champ as renowned for her looks as her four Grand Slam singles titles (the most recent at this year's French Open) is looking to add an Olympic gold to her already-crowded mantel. "It will be surreal," she said of playing in London for an Olympic medal rather than the Wimbledon Rosewater Dish. "It's just a unique opportunity for all of us, but I'm extremely thrilled that it's at Wimbledon. It's my favorite place to play tennis." Rightfully so: She earned her first Gram Slam title at age 17 at the All England Club.
